QUICK START GUIDE

UPX-HDMI+A HDMI 

Pass-through Universal Transmitter

Overview

The UPX-HDMI+A HDMI Pass-through Universal Transmitter Wallplate (

FG1402-53

enables users to connect HDMI sources directly to a projector while using an AVX-400 

or DVX-2100HD for audio and projector control. 
HDMI video passes through the wallplate directly to the connected projector. 

Note: UPX-HDMI+A Wallplates support pass-through of HDCP (High-bandwidth Digital 

Content Protection) information.

Stereo audio and projector control signals are carried via Cat-5 cable to the AVX-400 or 

DVX-2100HD allowing the audio to be mixed, processed and sent out the amplifier or 

line out. 
Use the pushbutton to select the HDMI input and corresponding audio source. 
The wallplate is available in US and Decora versions (see FIG. 1). Each wallplate mounts 

into single-gang back boxes. 

Note: AMX has evaluated several types of category cable for use with UPX wallplates. Of 

the cable types tested, CAT-5e offers optimal performance for UPX analog signal routing 

and AMX recommends Belden part number 1583a for best performance. CAT-6 category 

cable however has demonstrated wide variance in performance across manufacturers 

and cable part numbers, and therefore AMX recommends that customers needing to 

install CAT-6 cable pre-test the desired cable model with UPX wall plates at the desired 

lengths prior to installation.

AMX is currently evaluating additional Cat-6 and Cat-7 model numbers for compatibility, 

and will publish recommended model numbers upon results of the evaluation.
